MIAMI -- Former heavyweight boxing champ Trevor Berbick was hit on Friday with a four-year prison sentence for raping his children`s baby sitter.

Berbick, 39, is the second heavyweight fighter this year to be convicted of rape and sentenced to prison.

Mike Tyson, who took the heavyweight title from Berbick in 1986, was convicted of rape in March and sentenced to six years in prison.

Dade County Circuit Judge Thomas Wilson had postponed the sentencing twice before because of Berbick`s courtroom outbursts.

Wilson declared Berbick competent after weighing opinions from three court- appointed psychiatrists.

When the judge read the sentence, Berbick jumped to his feet and screamed at his family and prosecutors in the courtroom.

``You know what you did!`` he yelled. ``God will punish you!``

Berbick was convicted in February of raping a 26-year-old Fort Lauderdale woman who worked as the Berbicks` baby sitter. Berbick said the woman had an affair with him.

One psychiatrist testified Berbick suffers from delusions of grandeur. He said boxing might have caused neurological problems that have affected Berbick`s behavior.

``He sees himself as somewhat invulnerable -- his defeats are not really defeats, his knockouts are not really knockouts,`` said Sanford Jacobson.

During the sentencing hearing, Berbick seemed agitated and was told by the judge to settle down.

The last time Wilson tried to sentence Berbick he erupted into a long tirade in which he accused former heavyweight champ Larry Holmes, boxing promoter Don King and the Japanese for engineering a conspiracy against him.
